Stearman Kaydet Trainer

Historical Snapshot

The Kaydet, the two-seater biplane introduced by Stearman Aircraft Division of Boeing in Wichita, Kan., in 1934, became an unexpected success during World War II. Despite its almost obsolete design, its simple, rugged construction made it ideal as a trainer for novice pilots for the U.S. Army Air Corps (PT-13/-17) and Navy (NS/N2S).

The Kaydets had fabric-covered wooden wings, single-leg landing gear and an over-built welded-steel fuselage. Only radial engines were used. Between 1936 and 1944, Boeing built 8,584 Kaydets, in all versions, plus the equivalent of 2,000 more in spares.

Kaydets were widely used airplanes. In addition to sales to the U.S. Navy and the Army Air Corps, the trainers were sold to Canada, China, the Philippines, Venezuela, Argentina and Brazil for both military and civilian uses. Many were still in service in the early 1990s. Their slow, low-level flying capabilities made them particularly suitable for crop dusting and spraying.
